Mata Mata - Their flat heads, jagged skin and shells make them look like rocks or bark in the water. Even though they live in fresh water, these guys are lousy swimmers. They walk along the bottom and prefer to stay in shallow depths.
Every sea turtle has markings as distinct as fingerprints on their shells. In an attempt to save the turtles from slaughter, rescue groups are etching their shells with tools that 'ruin' them for collectors. YEA FOR THE TURTLES!
